Refactor a few report field calculations into separate functions.
...
For liblvm 'get' functions, we should share code with the reporting functions.
This means we need common code to return the values for the fields.
In this patch we refactor a few of the fields needed in liblvm.
Unfortunately, for the simple fields that do derefernces of structure
members (for example, vg_extent_count), we cannot call the common function
from the reporting infrastructure without more refactoring. The reason is
that the dereference of the simple fields is done deep inside the reporting
code (to get the generic "data" pointer), and the display function is a
generic 'size32' function. We can fix these issues later with more
refactoring.
Should be no functional change and the testsuite should cover any possible
regressions. The only fields in the report affected by this patch are:
vg_size, vg_free, and pv_mda_count.

Merge lv_is_displayable and lv_is_visible.
...
Displayable and visible is the same thing.
volumes_count(vg) is now vg_visible_lvs() and always
returns number of LVs from user perspective.

Separate PV label attributes which do not need parse metadata when reporting.
...
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.
This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.
(There should be no user visible change in output.)

Fix pvs segfault when run with orphan PV and vg_mda_size or vg_mda_free fields
...
We display '0' for these fields now in this case. Ideally these values are
undefined for an orphan PV but today there is no way to specify undefined
with display functions such as _size64_disp().

Add pv_mda_size to 'pvs' and vg_mda_size to 'vgs'.
...
Reports the size of the smallest metadata area in a PV or a VG.
Useful to confirm pvcreate --metadatasize or pvmetadatasize setting in
/etc/lvm/lvm.conf file.
NOTE: Actual value in these fields will most always differ from that
given in pvcreate options due to rounding and alignment effects.

Fix segfault when invalid field given in reporting commands.
...
Problem is dm_report_init() may return NULL and subsequent call to

Example:
pvs --nameprefixes --rows --unquoted --noheadings -opv_name,fred
Logical Volume Fields
---------------------
lv_uuid - Unique identifier
lv_name - Name. LVs created for internal use are enclosed in brackets.
...
Physical Volume Segment Fields
------------------------------
pvseg_start - Physical Extent number of start of segment.
pvseg_size - Number of extents in segment.
Unrecognised field: fred
